Enum SubMsStageKind 

#[non_exhaustive]
pub enum SubMsStageKind {
    HotPath,
    BatchOp,
    OneShot,
    Unspecified,
}

What kind of operation a stage records. Observers use this to choose histogram bucket boundaries that fit the measurement scale.

• HotPath: per-request operations under a sub-ms p99 budget (put, get_hit, enqueue, …).
• BatchOp: whole-structure / O(n) operations that run rarely - serialize, snapshot, replay, compact, full merge. Cost scales with size.
• OneShot: setup / teardown timings recorded once or a handful of times. Treated like BatchOp but with a lower-resolution histogram cap to avoid an occasional huge value blowing the bucket count.
• Unspecified: the default when a stage doesn’t declare its kind.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl SubMsStageKind

pub fn as_str(&self) -> &'static str

Lowercase snake_case identifier used as the subms.stage.kind OpenTelemetry attribute by sibling adapters. Kept on this side so the string is stable across crates without having to depend on subms-otel.

Trait Implementations

impl Clone for SubMsStageKind

fn clone(&self) -> SubMsStageKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SubMsStageKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SubMsStageKind

fn default() -> SubMsStageKind

Returns the “default value” for a type.

impl PartialEq for SubMsStageKind

fn eq(&self, other: &SubMsStageKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
